Description

Technical Field

[0001] The utility model relates to the technical field of computer data storage and reading and writing, in particular to a hard disk drive bracket and a hard disk. Background Art

[0002] In the existing hard disk structure, the drive bracket is a vital part. It realizes precise rotation through the cooperation of the pivot hole and the shaft, thereby driving the head to perform read and write operations on the disk. At present, in order to ensure the stability of the shaft in the pivot hole, a convex rib is usually set in the pivot hole, and a corresponding positioning groove is set on the shaft, and the two are inlaid and matched. However, the surface of the existing convex rib is mostly a smooth curved surface or a flat surface. This smooth design has gradually exposed many problems in practical applications. When the hard disk is running at high speed and frequently seeking operations, the friction between the smooth convex rib and the positioning groove is relatively limited, and it is difficult to provide sufficient resistance to resist external force interference under various complex working conditions. When the hard disk is vibrated or impacted, the smooth convex rib is easy to produce a small displacement in the positioning groove, and the drive bracket will rotate relative to the shaft, which will eventually lead to a decrease in the positioning accuracy of the head, increase the risk of data reading and writing errors, and also reduce the overall reliability and durability of the hard disk.

[0031] Reference Figure 1-Figure 2 , this embodiment provides a drive bracket of a hard disk, which is used to move a magnetic head driven by a drive device, and includes a first connecting arm 1, a bracket body 2 and a second connecting arm 3;

[0032] The first connecting arm 1 is disposed at one end of the bracket body 2, and the first connecting arm 1 is used to connect the magnetic head;

[0033] The second connecting arm 3 is disposed at one end of the bracket body 2 away from the first connecting arm 1, and the second connecting arm 3 is used to connect to the driving device;

[0034] A pivot hole 5 for accommodating a rotating shaft is disposed at one end of the bracket body 2 close to the second connecting arm 3 , and at least one convex rib 8 is disposed on the inner wall of the pivot hole 5 , and a corrugated surface 11 is formed on the convex rib.

[0035] In the above embodiment, the drive bracket of the hard disk is an extremely critical component in the hard disk, which is responsible for accurately moving the magnetic head under the drive of the voice coil motor (driving device) to achieve data reading and writing operations. Among them, the first connecting arm 1 is located at one end of the bracket body 2, and its main function is to connect with the magnetic head, establish a mechanical connection between the drive bracket and the magnetic head, so that the magnetic head can follow the movement of the drive bracket and move accurately on the disk; the bracket body 2, as the core structure of the entire drive bracket, plays a key role in supporting and connecting the first connecting arm 1 and the second connecting arm 3; the second connecting arm 3 is arranged at the end of the bracket body 2 away from the first connecting arm 1, it is connected to the voice coil motor, and is an important link for transmitting the power of the voice coil motor to the entire drive bracket. A pivot hole 5 is arranged at one end of the bracket body 2 close to the second connecting arm 3. The pivot hole 5 is used to place the rotating shaft. Through the rotating shaft, the drive bracket can be stably connected to the bottom plate of the hard disk and flexibly rotate around the rotating shaft as the center to achieve accurate movement of the magnetic head in the radial direction of the disk. At least one rib 8 is arranged on the inner wall of the pivot hole 5, and the number is at least one, and it bulges toward the center of the pivot hole 5, and a corrugated structure is arranged on the rib 8, so that a corrugated surface 11 is formed on the surface of the rib 8.

[0036] When the hard disk starts working, the voice coil motor receives a control signal and starts to operate, driving the rotation of the second connecting arm 3, and then driving the rotation of the bracket body 2 through the second connecting arm 3. The bracket body 2 rotates around the shaft, driving the first connecting arm 1 and the connected magnetic head to move above the disk. The first connecting arm 1, the bracket body 2 and the second connecting arm 3 are integrated into one piece. The first connecting arm 1 and the second connecting arm 3 are respectively located at the two ends of the bracket body 2, so that the driving bracket is more reasonable in terms of force and motion transmission. The pivot hole 5 is close to the second connecting arm 3. This is because the position close to the power source (voice coil motor) is conducive to better transmission of torque when the driving bracket rotates, reducing energy loss. When the shaft is inserted into the pivot hole 5, the convex rib 8 interacts with the surface of the shaft. The clamping method between the convex rib 8 and the shaft can be Interference fit, that is, the rib 8 is embedded in the positioning groove of the shaft. At the same time, when the rib 8 cooperates with the positioning groove on the shaft, the corrugations of the corrugated surface 11 can form a microscopic meshing with the inner wall of the positioning groove, just like the meshing between gears. The raised part of each corrugation is in close contact with the inner wall of the positioning groove and fits with each other, which greatly increases the number of contact points. Therefore, by forming the corrugated surface 11 on the rib 8, the friction between the rib 8 and the positioning groove of the shaft is greatly increased. The corrugated structure can prevent the entire drive bracket from rotating relative to the shaft when the hard disk is vibrated or impacted, thereby ensuring the stability of the drive bracket, improving the positioning accuracy of the magnetic head, reducing the risk of read and write errors, effectively reducing the wear of the drive bracket and the shaft, reducing the probability of component failure, extending the life of components, and significantly improving the reliability and durability of the hard disk.

[0037] Reference Figure 1 In one embodiment, the bracket body 2 is further provided with at least one heat dissipation hole 6 spaced apart from the pivot hole 5 , and the heat dissipation hole 6 is located between the pivot hole 5 and the first connecting arm 1 .

[0038] In the above embodiment, the heat dissipation hole 6 is arranged on the bracket body 2, between the pivot hole 5 and the first connecting arm 1, and the number of the heat dissipation hole 6 is at least one. The main function is to dissipate the heat generated by the movement of the magnetic head in time during the operation of the hard disk. The distribution of the heat dissipation hole 6 between the pivot hole 5 and the first connecting arm 1 can take into account the heat dissipation requirements of the entire drive bracket, ensuring that the heat generated by the movement of the front-end magnetic head is dissipated to the space of the hard disk through the heat dissipation hole 6, preventing the heat from being transferred to the voice coil at the rear end, ensuring that the voice coil will not heat up due to the heat conduction generated by the movement of the front-end magnetic head, thereby ensuring the stable performance of the voice coil.

[0039] Reference Figure 1In one embodiment, the heat dissipation hole 6 is in the shape of a strip hole, and the strip hole is arranged along the extension direction of the drive bracket of the hard disk, the heat dissipation hole 6 includes a first heat dissipation hole 60, and a second heat dissipation hole 61 arranged opposite to the first heat dissipation hole 60, the first heat dissipation hole 60 is located between the second heat dissipation hole 61 and the first connecting arm 1, the second heat dissipation hole 61 is located between the first heat dissipation hole 60 and the pivot hole 5, and the length of the first heat dissipation hole 60 is greater than the length of the second heat dissipation hole 61, and the width of the first heat dissipation hole 60 is less than the width of the second heat dissipation hole 61.

[0040] In the above embodiment, when the heat dissipation hole 6 is in the shape of a strip hole, the strip hole is preferably in the shape of a runway, and the strip hole is arranged along the extension direction of the drive bracket of the hard disk, that is, the heat dissipation hole 6 extends along the first direction X, and the heat dissipation hole 6 includes a first heat dissipation hole 60 and a second heat dissipation hole 61. The first heat dissipation hole 60 and the second heat dissipation hole 61 are both hole structures for heat dissipation opened on the bracket body 2. The first heat dissipation hole 60 and the second heat dissipation hole 61 are arranged opposite to each other. The first heat dissipation hole 60 is located between the second heat dissipation hole 61 and the first connecting arm 1, closer to one end of the first connecting arm 1 where the magnetic head is located, and the second heat dissipation hole 61 is located between the first heat dissipation hole 60 and the pivot hole 5, closer to one side of the power source (the driving device connected to the second connecting arm 3), and the length of the first heat dissipation hole 60 is greater than the length of the second heat dissipation hole 61, and the width of the first heat dissipation hole 60 is less than the width of the second heat dissipation hole 61, wherein the length direction is the first direction X, and the width direction is the second direction Y. Therefore, the first heat dissipation hole 60 and The relative arrangement and specific position distribution of the second heat dissipation holes 61 form an efficient heat dissipation path. The first heat dissipation hole 60 is close to the magnetic head and can dissipate the heat generated by the operation of the magnetic head in time. Since the width of the driving bracket gradually increases in the second direction Y when the length of the driving bracket extends along the first direction X, so that it forms a cone-like shape, the first heat dissipation hole 60 is closer to the end of the driving bracket where the width of the magnetic head is narrower. While ensuring the rigidity of the driving bracket, the longer length and narrower width can effectively dissipate the heat generated by the movement of the magnetic head. The second heat dissipation hole 61 is located between the first heat dissipation hole 60 and the pivot hole 5. It has a shorter length and a wider width than the first heat dissipation hole 60. While ensuring the rigidity of the driving bracket, it further effectively dissipates the heat generated by the movement of the magnetic head. Therefore, through the first heat dissipation hole 60 and the second heat dissipation hole 61, while ensuring the rigidity of the entire driving bracket, the heat generated by the movement of the magnetic head can be effectively dissipated.

[0041] Reference Figure 1In one embodiment, a first specified distance is formed between the first heat dissipation hole 60 and the first connecting arm 1, a second specified distance is formed between the first heat dissipation hole 60 and the second heat dissipation hole 61, and a third specified distance is formed between the second heat dissipation hole 61 and the pivot hole 5, the length of the second specified distance is less than or equal to the length of the first specified distance, and the length of the first specified distance is less than or equal to the length of the third specified distance.

[0042] In the above embodiment, there is a specific distance relationship between the first heat dissipation hole 60 and the first connecting arm 1, the second heat dissipation hole 61 and the pivot hole 5. When these four components are located on the same center line, the distance between the end of the first heat dissipation hole 60 close to the first connecting arm 1 and the connection between the bracket body 2 and the first connecting arm 1 is the first specified distance, which affects the efficiency of heat dissipation near the magnetic head; the distance between the end of the first heat dissipation hole 60 close to the second heat dissipation hole 61 and the end of the second heat dissipation hole 61 close to the first heat dissipation hole 60 is the second specified distance, and its length is less than or equal to the first specified distance. This arrangement helps to optimize the distribution of heat dissipation; the distance between the end of the second heat dissipation hole 61 close to the pivot hole 5 and the side of the pivot hole 5 close to the second heat dissipation hole 61 is the third specified distance, and the first specified distance is less than or equal to the third specified distance, so that the heat dissipation hole 6 can reasonably dissipate heat in the magnetic head area, ensuring the temperature balance of the entire drive bracket, wherein the direction of the specified distance is the first direction X.

[0043] Therefore, the reasonable setting of the first specified distance ensures that the first heat dissipation hole 60 can effectively dissipate the heat generated in the head area, preventing the head from overheating and affecting the reading and writing accuracy; the limitation of the second specified distance makes the heat dissipation transition between the first heat dissipation hole 60 and the second heat dissipation hole 61 smooth, avoiding local overheating or uneven heat dissipation; the arrangement of the third specified distance ensures that the second heat dissipation hole 61 can take into account the heat dissipation generated by the drive device near the pivot hole 5. On the whole, the synergistic effect of the three specified distances enables the heat to be evenly dissipated from the head area, the middle of the bracket body 2 to the vicinity of the power source, thereby maintaining the temperature stability of each part of the drive bracket, reducing material deformation and performance changes caused by temperature differences, improving the reliability and stability of the drive bracket, and thereby ensuring the accuracy and continuity of hard disk data reading and writing.

[0044] Reference Figure 1 In one embodiment, the first heat dissipation hole 60 includes a main body 601, and a first arc portion 602 and a second arc portion 603 respectively located at two ends of the main body 601, the first arc portion 602 is located between the main body 601 and the first connecting arm 1, the second arc portion 603 is located between the main body 601 and the second heat dissipation hole 61, and the diameter of the first arc portion 602 is smaller than the diameter of the second arc portion 603.

[0045] In the above embodiment, the first heat dissipation hole 60 is composed of a main body 601, a first arc portion 602 and a second arc portion 603. The main body 601 is the main channel part of the heat dissipation hole 6, the first arc portion 602 is located between the main body 601 and the first connecting arm 1, the first arc portion 602 is close to the head area, the second arc portion 603 is located between the main body 601 and the second heat dissipation hole 61, the first arc portion 602 is close to one end of the head, and the second arc portion 603 is close to one end of the second heat dissipation hole 61. Since the shape of the drive bracket is similar to a cone, the diameter of the first arc portion 602 is smaller than the diameter of the second arc portion 603. Therefore, while ensuring the rigidity of the entire drive bracket, the different diameters at both ends of the first heat dissipation hole 60 can effectively dissipate the heat generated in the head area to prevent the head from overheating and affecting the reading and writing accuracy.

[0046] Reference Figure 1 In one embodiment, a receiving groove 4 is provided in the second connecting arm 3 and is recessed toward the bracket body 2 . The receiving groove 4 is used to place the voice coil of the driving device.

[0047] In the above embodiment, in the drive bracket structure of the hard disk, the second connecting arm 3 is a key part connecting the drive device and the bracket body 2. The accommodating groove 4 arranged inside the second connecting arm 3 is a space specifically used to place the voice coil of the drive device. The accommodating groove 4 is recessed toward the bracket body 2 to form a groove-like structure, which provides a stable placement position for the voice coil. The top opening width is larger than the bottom width, similar to a trapezoidal groove with a larger top and a smaller bottom. This shape makes it easier to place the voice coil, but after placement, it can be better limited and is not easy to fall out of the groove. The second connecting arm 3 is composed of a first arm 30 and a second arm 31, which are arranged opposite to each other to jointly support and fix the accommodating groove 4. The length of the first arm 30 is greater than or equal to the length of the second arm 31. This length difference may be related to the force balance of the overall structure. A coil limiting portion 7 is provided at one end of the first arm 30 away from the bracket body 2. The limiting portion protrudes toward the accommodating groove 4. When the voice coil is placed in the accommodating groove 4, the coil limiting portion 7 can limit the voice coil from one side to prevent it from excessive longitudinal displacement in the groove, wherein the longitudinal displacement direction is the first direction X. Although the second arm 31 does not have the coil limiting portion 7, it cooperates with the first arm 30 to surround and assist in fixing the voice coil from the opposite direction. The entire second connecting arm 3 ensures the stable installation of the voice coil in the driving bracket through its unique structural design, thereby ensuring the reliability of power transmission between the driving device and the driving bracket.

[0048] Therefore, the shape of the accommodating groove 4 makes the voice coil coil easy to install and can effectively limit its position to prevent it from moving due to vibration and other factors when the hard disk is working, thereby ensuring the stability of the relative position of the voice coil coil and the driving bracket; the coil limiting portion 7 further strengthens the constraint on the voice coil coil to prevent it from shaking in the horizontal direction, ensuring that the magnetic field generated by the voice coil coil can stably act on the driving bracket to achieve accurate power transmission; the length design and matching method of the first arm 30 and the second arm 31 optimize the structural strength and force distribution of the second connecting arm 3, making it more stable and reliable when bearing the driving force of the voice coil motor, which not only improves the working efficiency of the driving bracket and reduces energy loss, but also extends the service life of the voice coil coil and the driving bracket, and improves the overall performance and reliability of the hard disk.

[0049] Reference Figure 1 In one embodiment, at least one limiting groove 9 and a limiting protrusion 10 are provided on the bracket body 2, and the limiting groove 9 and the limiting protrusion 10 are respectively arranged on the side edges of the bracket body 2 relative to each other.

[0050] In the above embodiment, the limiting groove 9 and the limiting protrusion 10 are important limiting structures arranged on the side of the bracket body 2. The limiting groove 9 is a groove-shaped structure formed by inward depression on the side of the bracket body 2. Its shape and size are different from the limiting protrusion 10 according to usage requirements. The limiting protrusion 10 is a part that protrudes outward from the side of the bracket body 2. They are respectively arranged on the two side edges of the bracket body 2 relatively to each other, and the number is at least one. The limiting groove 9 and the limiting protrusion 10 are integrally formed with the bracket body 2 and become a part of the bracket body 2. When the drive bracket is in the installation position inside the hard disk, the limiting groove 9 and the limiting protrusion 10 are distributed on the side of the bracket body 2 and cooperate with the outer shell or other internal structures of the hard disk. When the hard disk starts working, the limiting groove 9 and the limiting protrusion 10 effectively prevent the drive bracket from excessive rotation during the rotation process, ensuring that the magnetic head can be accurately positioned on the target track of the disk to perform accurate data reading and writing operations.

[0051] Reference Figure 1-Figure 2 The utility model also includes a hard disk, including a drive bracket of the hard disk described in any of the above embodiments.

[0052] In the above embodiment, the hard disk includes a drive bracket of the hard disk. In terms of heat dissipation, the reasonable layout of the heat dissipation holes 6 and the optimization of related structures can effectively dissipate the heat generated during operation, stabilize the internal temperature of the hard disk, ensure the accuracy of data reading and writing, and reduce the risk of data loss or hard disk damage due to overheating. Secondly, the fine design of each component of the drive bracket, such as the stable placement of the voice coil by the second connecting arm 3, the stabilizing effect of the convex rib 8 at the pivot hole 5 on the rotating shaft, and the precise positioning of the upper limit groove 9 and the protrusion of the bracket body 2, together improve the stability of the overall structure of the hard disk, which not only reduces the failure caused by loose or displacement of components, but also prolongs the service life of the hard disk, improves the reliability of the hard disk in various complex working environments, and provides users with a more stable and efficient data storage solution.
